I do not recommend this airbnb. For a short stay, the apartment can do the trick if you are not too careful about the cleanliness and you don't want to cook.  On the other hand, to be avoided for long stays :  - apartment not clean (hair in the bed, dirty floor, stains on the sofa, ...) and no cleaning equipment. - kitchen not really functional (1. the fridge only works with an electronic card which is also the key to enter the apartment, so when you are away, there is no electricity in the apartment 2. only one tiny sink in the bathroom). - You will be asked for a deposit from which your charges (electricity, water and internet) will be deducted. But the owner applies the rates that suit him, without referring to the current rates: you pay more than you consume.  Clearly, for the same price, you can easily find a better accommodation in Bangkok with more facilities.
I note nevertheless that the apartment is identical to the photos and the district is typical and rather pleasant. In addition, the owner responds quickly.
